While those “expert guessers” have no actual credentials that say they can guess people’s ages, the secret to their success sometimes springs from a variety of visual tells. In my case, I may never act my age, but factors such as height, the depth of your voice, and the presence of features like facial hair or wrinkles can lead a relative stranger in the right direction.

Your daily routines could also be impacting your perceived age. Who knew that habits like sleeping on your side or eating particular foods could age you more quickly? Here are 10 everyday habits that you can break if you want to slow down time.

1. Drinking with straws


Pursing your lips while drinking through a straw can cause wrinkling around the mouth. Instead, it is recommended to drink directly from the glass.

2. Bad posture


Bad posture can impact your spinal alignment and increase tension in muscles and bones. Constant slouching can cause permanent abnormalities and as well as fatigue and pain.

3. Eating low-fat diets


Low-fat diets deprive the body of healthy Omega-3s that helps keep our skin soft and smooth. A lack of these fatty acids will cause early wrinkling and drying of the skin.

4. Sleeping on your side


While sleeping on your side, your face gets crammed into your pillow. This can reportedly cause wrinkling of your cheeks and chin. The best position for a good night’s sleep is laying on your back.

5. Wearing sunscreen only on vacation


UV exposure is one of the major causes of premature aging. You may only wear sunscreen during the summer months or on vacation, but experts believe that wearing sunscreen every day works wonders when it comes to skin care.
